HECO CONTRACTOR ACCIDENTALLY CAUSES SEWAGE SPILL NEAR SAND ISLAND WASTEWATER TREATMENT PLANT
A private contractor working for Hawaiian Electric Company inadvertently drilled into a 48-inch pressurized sewer line near the Sand Island Wastewater Treatment Plant (WWTP) this morning (Thursday, July 22), causing an estimated 20,000 gallons of untreated wastewater to spill into a nearby storm drain before the flow was diverted back into the wastewater treatment system.
The incident occurred at about 9:30 a.m. on the treatment plant property near the Parkway Wastewater Pump Station (WWPS). The ruptured underground line leads from the Hart Street WWPS to the Sand Island WWTP. The spilled wastewater in the storm drain did not enter Honolulu Harbor.
While the spill continues, the flow is being pumped to the Parkway WWPS. Crews are working to ultimately divert the flow to an old force main, which will take about three days to reconnect. The broken force main is expected to be repaired in two weeks.
The State Department of Health has been notified, and the area has been disinfected and deodorized. Warning signs have been posted and sampling to check for contamination is underway.
